If it's so important to install a catch can on engines with an EGR, why don't they come stock? The EGR on my Ford Everest failed after 135,000km and cooked the engine for a $25k repair bill. EGR is the worst addition to diesel engines sine their inception

[@unofficialtester1545]

@@maxxfx4767 because EURO V and VI emissions which manufacturers abide by in order to sell their vehicles into Europe do not take into account countries that do not see snow. Further more, you can drive for 5 hours in any direction and pass through 2 or 3 countries. In Australia, 5 hours drive would not even get me anywhere near my states capital city. Engines for Euro specs are only designed for short start\stop....not long distance driving. hence why aftermarket addons are needed on vehicles that meet Euro specs but are sold in countries outside of Europe. My town hits a maximum of 42 degrees celsius and roughly 5 degrees celsius in winter. 5 degrees C in winter only happens once every 3 years, usually our average is 13 - 15 degrees Celcius for the winter months. Engines in Europe rarely get to operating temperature before they are shut down and the driver reaches their destination.

This is 100% my point why Chemical cleans are no good for an engine, all that built up crud gets forced through all the area's you pointed out. Cost more for a mechanical removal and clean but all that crap goes in the bin and not through your engine. Catch can can only do there job if fitted from near new, There great, but for a slightly older rig the mechanical clean must come first then fit the can. Now let the money making chemical cleaning guys unleash and tell me where they recon the crap goes if not through the engine, Thanks for your video Murray in Redcliffe QLD.

[@leighbaragwanath]

If I install the catch can, do I need to clean up anything in-line of the can. ie; clean out the system of which it protects?

[@einfelder8262]

The explanation of how EGR "saves" your engine by de-stressing it is pretty much a politically correct discourse. Yes it reduces NOx emissions, but NO it doesn't give an engine better economy or longevity. To cruise at a certain speed requires a certain amount of energy from the fuel - if you reduce fuel and O2 by filling half the chamber with inert gas you reduce the power output and hence the vehicle will slow down until you press the accelerator further to add more fuel again. Your economy actually gets worse. I've had a Provent on my Patrol since 5000k from new, and the inlet was already saturated with oil - dripped out of the intercooler when I took it off to wash it out. The Provent is indeed an elite quality catch can/oil separator.

[@AaronCook83]

Not sure if the guy knows how diesels operate vs gas. If the ECU is actually reducing fuel, your right foot will be compensating. Give me all the oxygen and all the temperature, the NOx can be treated in other ways.

[@wazza33racer]

exactly. The engine breathing in soot is just destructive to its internals.........and less oxygen thanks to EGR works against all the progress in turbocharging and intercoolers to increase oxygen density. Talk about politically correct bull manure.

Interesting vid but also opposite to what my mechanic has told me with the D40. He says egr block is the way to go and I don't need a catch can after that as the oil will burn off properly not mixing with the exaust gas. He also said the opposite with fuel consumption as everyone they have done the egr block on has reported better fuel consumption and performance. Be nice to get some consistent answers

Change your mechanic. He's an idiot.

[@renbenism]

I am a mechanic and I agree,block the egr then the oil vapour won't mix with exhaust gas and won't gum up.Tiny amounts of oil in the intake is fine,will just burn up.The downside is you won't be supporting commercials such as this

[@einfelder8262]

@@renbenism My intercooler was literally dripping with oil after 5000ks. The oil mist is harmful to the turbo that it passes through and coats the intercooler so it doesn't work nearly as well and it coats the inside of the inlet where the extreme cylinder heat will bake the crud on, even without the addition of EGR. The crankcase blowby fumes are not pure clean oil - the collection of trapped fumes that comes out of my Provent is disgusting black oil. I remind readers that 50% of mechanics are below average, and I remind readers of the oft publicised videos that trap "mechanics" ripping customers off. Message is don't trust a mechanic because he says he's a mechanic. Think logically. Fit a catch can or sell your vehicle before 100,000-150,000ks.

I AM A HUGE FAN OF 4WD ACTION GREAT VIDEOS THANK YOU GUYS! The Manufactures now build cars like throw away cigarette lighters due to fact most of the engines are no good unless you mod them cough cough, they have DPF fitted creating higher engine temperature due to the restriction in the exhaust an EGR that recirculates all the dirty final emission output especially when they are not closing correctly causing smoke less mpg and higher nox! ohhhh and mr Mann filter man..........an egr recirculates the hot exhaust gas so this make the burn temp higher not lower !! I do like the catch can though its good that the crank case oil is not been allowed to enter the combustion process

[@crooked-halo]

I've read the opposite, that since the exhaust gas that recirculates is always losing heat after combustion, the EGR allows _cooler_ temperatures in the cylinders, _not_ higher. This makes more sense logically than what you said "makes the burn temp higher."

[@yeerboi]

Great video!

[@driveandsurvive]

I had a look at a EGR system with a catch can. It still had plenty of carbon deposits. It may well slow the deposits down as it catches the oil and the soot has less ability to stick to the EGR components and the inlet manifold, but I wonder if the small amount of oil that gets through without a catch can, helps to lubricate any deposits that make their way into the cylinders? Essentially, is the grit post catch can more abrasive as a result of the oil removal?

(because the o2 sensor sensors fuel and supplies the right amount of diesel). Then you can catch 100% of the oil, it would still lower fuel consumption and be 100% better for environment and the engine, and the oil discard process might be higher but a lot easier and the whole system works better all round?? 💁🏼‍♂️ Can an egr sensor be deleted from ecu ?

[@4x4maximus]

Incorrect! The problem is the EGR soot. You need to reduce that by a blanking plate, generally a 7mm to 8mm hole blanking plate will significantly reduce build up. You have butterfly valves and the valves that need lubrication from vented engine gas. Diesel use to get this lubrication before direct injection. Now diesel is directly injected it bypass the additional lubrication diesal inlets need. Reduce EGR soot and leave the oil, the oil will act as a cleaner and remove the reduced soot. Taking away the lubrication the soot will still cake your inlet. Reduce EGR and keep engine gas recirculation. It's minimal oil! Have you ever check your oil and noticed it dropping? No! If your worried about intercooler reducing its cooling efficiency, pull it off every service and high pressure clean it out. It's only 4bolts and 2 hose clamps. Again it's not blanking it reducing EGR by 90% it still gets through just slower

This is a good point everyone may have missed if it's true but what you are saying is that the swirl-flaps fitted in the inlet manifold need lubrication from the blow-by oil?

Can you put a catch cam on a petrol 4wd

[@fitzyholden1036]

Agree and have fitted one to my Landcruiser. Got to wonder why they are not fitted by the vehicle manufacturers.

[@UnacceptableViews]

they aren't fitted as standard because 90% of people wouldn't empty them at the intervals they need to be emptied. sucking in actual liquid oil would cause more damage than oily gases.

Hi all. Do i need a catch can on a 60 series 2H.THANKS.

[@craigwoodward4566]

Never been a big fan of compression ignition.(diesel) .Next one i buy will be a Y62. Albiet with a bit more fuel use .

[@einfelder8262]

Direct injection petrol engines have the exact same problem ad diesels. There ya go.

[@tray2465]

And change oil regularly helps 😃

[@BenzinioB]

Well this is interesting product didn't know it exist. But does the installing of catch can ruin the guarantee of a new car? And can it be mounted in diesel hatchback not just big 4x4

Easy way is to ask vehicle manufacturers service department. Yes will need custom kit for hoses. Don't buy a fake provent get German made mann hummel provent 200
